I can tell you that only spending $*, it's well constructed and I feel safe being 6'2" and 230lbs. It will hold up to 6'6 and 300 and it has some heft so I would tend to believe it. I felt perfectly safe on it and can tell you that for my first time on it, my back was pain free the entire time, no pressure, etc....studies are inconclusive and anecdotal at best regarding inversion therapies on low back pain but I'll try it before any surgical procedures. I injured myself about 5 weeks ago and I'm on the mend because of sheer male Stubbornness and my belief that pain is weakness leaving the body. Give me a few days on this this for better viewpoint, but for a product....it's solid. Easy to put together and strong. Does what it says. Had some shipping issues but customer service took care of it expeditiously.
These are more bulky than steel plates so not easy to fit desired weight on a hand bar bell. They come with filler already installed in heavy plastic shell.
